DRV201A in Drones

Other Parts Discussed in Thread: DRV201A

Hi Team,

I came across the DRV201A as an auto focus lens driver that can be used in digital still camera applications. How appropriate would this be for use in a drone application where we would be interested in using it to capture video? A drone would be flying around in 3-D space causing the subject to come in and out of focus very rapidly. Also if you have any type of recommendations as to what type of microcontroller to use in this application, that would be great as well.

Any feedback would be appreciated. Thank you!

    Hi Akesh,

    I am not sure I understand. The DRV201A would normally be part of the camera assembly. Assuming you are building the camera assembly, this is appropriate.

    For control, a micro with an I2C interface will do. The question arises from the system requirements. Assuming the firmware is handling the autofocus, the demand on the processor would determine the microcontroller required.

    Hi Rick,

    Thank you for the response. My initial question was more towards using the DRV201A in video recording applications vs. photo taking applications. A common application listed for the part is still cameras (which I assume means taking photos and not video). I was wondering if this would be appropriate in video recording where the focus may have to be adjusted several times per second depending on the movement of the drone.

    Hi Akash,

    Just a thought: Is there truly a need for auto focus in a fast paced video recording application? With my limited knowledge on the matter, I do know that using a camera lens with a larger depth of field can improve your minimum and maximum focus range without the need to constantly attempt to regain focus.

    As for designing a quad-copter, we have a TI Design in the works that will be releasing to the web in a few months that you will be able reference to.

    Regards,
